What is a ballast mat?
A ballast mat is a resilient layer, often made from recycled rubber or polyurethane, installed beneath railway ballast to reduce vibrations, suppress noise, prevent ballast degradation, and improve load distribution for more stable and quieter ballasted track systems, especially in urban areas or on bridges. They act as a cushion, protecting the track structure and underlying ground from excessive dynamic forces, extending maintenance intervals, and enhancing environmental comfort.
Technical specifications of under ballast mat:

| Thickness Range | Single layer of elastomer: 10 to 30 mm |
| Non-woven protection layer: 1.8 mm | |
| Total system thickness: 11.8 to 51.8 mm | |
| Geometry | Flat or wavy |
| Density Range | 710 to 1000 kg/m³ |
| Supply Form | Rolls |
| Joints | Not required |
The Ballast Mat Damper produced by GNEE RAIL is a mat made from natural recycled rubber. Natural rubber gives optimal properties for resilience, anti vibration performance with a low damping factor, fatigue and longevity resistance.
It helps reducing the vibration noise of ballasted track in urban areas and/or can also increase the life cycle of the ballast. It also helps compensating reduction of the ballast thickness where it is not high enough. Finally it helps reducing impact force that structures may experience over time (such as Bridges).
The Ballast Mat Damper is suited for tramways or subways as well as for train lines in urban areas.
A geotextile membrane on top of the ballast mat damper is required in order to optimise product lifespan. It increases the resistance against ballast stresses and it protects the mat against dust from ballast wear.
GNEE RAIL provides exceptional elastic rail pads of various types for high-speed railways, normal-speed railways, and cranes. Especially the rail pads made of rubber, EVA, TPEE, and HDPE are very popular with customers. Our railway rubber pads fit the rails such as UIC54, UIC60, BS80lbs, BS100lbs, etc. We have more than 130set of machines in our production lines which can reach an annual production capacity of up to 2000, 000 pieces of rail pads. We offer a wide range of rail pads and other track materials at competitive prices.
